The sensation of fatigue in muscles after prolonged strenuous physical work is primarily caused by (d) Accumulation of lactic acid. During intense exercise, when oxygen demand exceeds supply, the body resorts to anaerobic metabolism, breaking down glucose without oxygen. This process produces lactic acid as a byproduct, leading to an increase in acidity within the muscles.
The buildup of lactic acid contributes to muscle fatigue and discomfort, resulting in a burning sensation and reduced muscle function. However, it’s important to note that fatigue can also be influenced by other factors such as depletion of glycogen stores, minor muscle fiber damage, and central nervous system fatigue.
While decreased oxygen supply (a) can contribute to fatigue in prolonged exercise, it’s primarily the buildup of lactic acid that causes the acute sensation of muscle fatigue during intense physical activity.

Carbohydrates give an athlete more energy quickly. Unlike fats, which are metabolized slowly, and proteins and vitamins, which do not directly provide energy, carbohydrates are efficiently converted into glucose during digestion. This glucose serves as the primary fuel for muscles during high-intensity exercise.
Carbohydrates offer rapid energy replenishment, making them ideal for athletes needing quick bursts of energy for performance. Additionally, carbohydrates can be stored in the body as glycogen in the muscles and liver, providing a readily available energy reserve for prolonged physical activity.
While fats and proteins play essential roles in the body, such as providing long-term energy storage and supporting muscle repair and growth, respectively, carbohydrates are the preferred source of energy for immediate fuel needs, particularly during intense exercise or athletic competition.
Carbohydrates are stored in the human body in the form of Glycogen. Glycogen is a complex polysaccharide and serves as the primary storage form of glucose in animals, including humans.

Carbohydrates are stored in the human body in the form of Glycogen. Glycogen is a complex polysaccharide and serves as the primary storage form of glucose in animals, including humans. It is stored primarily in the liver and muscles.
When excess glucose is present in the bloodstream, particularly after consuming a meal high in carbohydrates, insulin signals cells to absorb glucose for energy production or storage. Some of this glucose is converted into glycogen through a process called glycogenesis. Glycogen serves as a readily accessible energy reserve that can be quickly broken down into glucose when blood sugar levels drop, such as during fasting or physical activity.
This glycogen storage system helps regulate blood sugar levels and ensures a steady supply of glucose to meet the body’s energy demands, particularly during periods of increased activity or when dietary carbohydrates are not available.

The nutrient that provides maximum energy is Carbohydrate. Carbohydrates are the body’s primary source of energy, providing 4 calories per gram. They are efficiently converted into glucose during digestion, which is then utilized by cells for energy production through cellular respiration.
While proteins and fats also provide energy, carbohydrates are the preferred and most rapidly metabolized energy source. Protein provides 4 calories per gram, but its primary role is in building and repairing tissues rather than serving as an energy source. Fats provide the most concentrated energy, with 9 calories per gram, but they are metabolized more slowly compared to carbohydrates.
Vitamins and mineral salts do not directly provide energy but play crucial roles in various physiological processes within the body, such as metabolism, immune function, and overall health. However, they do not serve as a direct source of energy like carbohydrates do.

Honey mainly contains Carbohydrate. It is primarily composed of natural sugars, predominantly glucose and fructose, with smaller amounts of other sugars such as sucrose and maltose. These sugars provide the sweet taste and energy content of honey.
While honey is primarily known for its carbohydrate content, it also contains trace amounts of other nutrients such as enzymes, amino acids, vitamins, and minerals. However, these nutrients are present in relatively low concentrations compared to the carbohydrate content.
Honey’s nutritional composition can vary depending on factors such as floral source, processing methods, and storage conditions. Despite its carbohydrate-rich nature, honey is often valued not only for its sweet flavor but also for its potential health benefits, including antioxidant properties, wound healing effects, and soothing qualities for coughs and sore throats.

The sugar that provides instant energy is Glucose. As a monosaccharide, glucose is the simplest form of sugar and is quickly absorbed into the bloodstream following digestion. Once in the bloodstream, glucose can be transported to cells throughout the body, where it is readily utilized in cellular respiration to produce ATP, the primary energy currency of cells.
Glucose is particularly important for providing rapid energy during times of increased energy demand, such as exercise or periods of low blood sugar. Its ability to quickly elevate blood glucose levels makes it an essential nutrient for maintaining optimal bodily functions and supporting physical and cognitive performance.
While other sugars like lactose, cellulose, and maltose also provide energy upon digestion, they are not as readily absorbed or metabolized as glucose, making glucose the preferred choice for instant energy needs.
The main component of honey is Fructose.

While honey contains various sugars, including glucose and sucrose, fructose is the predominant sugar, typically constituting around 38% to 44% of honey’s total sugar content. This natural sugar imparts sweetness to honey and contributes to its distinctive taste.
Fructose, a monosaccharide, is a simple sugar that is easily absorbed by the body, providing a quick source of energy. Its presence in honey also contributes to its characteristic viscosity and ability to crystallize over time.
Honey’s composition can vary depending on factors such as floral source, processing, and environmental conditions. However, regardless of these variations, fructose remains a fundamental component, contributing to honey’s nutritional profile and making it a popular natural sweetener and ingredient in various culinary and medicinal applications.

The cover of a capsule is commonly made of Cellulose, a polysaccharide found in plant cell walls. Cellulose is chosen for its inert properties, allowing it to form a stable and protective barrier around the medication or supplement contained within the capsule. This protective barrier helps preserve the integrity of the contents, shielding them from external factors such as moisture, light, and air, which could degrade the medication.
Cellulose capsules are preferred for their compatibility with a wide range of substances, including pharmaceutical drugs and dietary supplements. Additionally, cellulose capsules are typically vegetarian or vegan-friendly, making them suitable for individuals with dietary restrictions. Overall, the use of cellulose as the capsule material ensures the safe and effective delivery of the encapsulated substance while also meeting various dietary and pharmaceutical requirements.

Carbohydrates are the essential components of food, serving as the primary source of energy for the body. They encompass various forms, including simple sugars like glucose and complex carbohydrates like starch. Upon consumption, carbohydrates are broken down during digestion into glucose molecules, which are then absorbed into the bloodstream to provide fuel for cellular activities and bodily functions.
In addition to providing energy, carbohydrates play a crucial role in maintaining overall health. They are a source of dietary fiber, which promotes digestive health by regulating bowel movements and supporting the growth of beneficial gut bacteria. Carbohydrates also contribute to satiety, helping to control appetite and manage weight.
While carbohydrates are vital for energy production and maintaining health, it’s essential to consume them in moderation and prioritize complex carbohydrates from whole foods like fruits, vegetables, whole grains, and legumes to ensure a balanced diet and optimal nutrition.
